To ALLWHOM l11' MAY coNcEnN:

Be it yknown that I, OLIVER C. Swami, oi' Albany, in the countyl of Albany,- end State of New York, have invented a newand improved Machine'for Drying and Finishing Tubular If'abrics; and I do hereby declare that the following is a full, clear, andexact description thereof,'which will enable others skilled in the art to make and use the same, reference being hdd to the accompanying drawings, forming part of this specication, in vwhich-v Figure 1 represents a side elevation, partly in section, of my improved machine for drying tubular fabrics. Figure 2 is a vertical cross-section ofthe same, the'plane of section being indicated by the line z z, iig. 1. Figure 3 is a. planer top view of the drying-apparatus. Figure 4 is 'a' plan view of the bottom ofthe drying-apparatus.l Similar letters of reference indicate like parts.

This invention relates to a machine for drying, stretching, brushing, heating, and calendering knitted or other tubularfabric; and consists in such an arrangement of all the parts that the said 'fabric is completely nished and wound upon a roller, after having .passed through the machine. provision being made for retaining the meshes in straight lines, and for preventing the fabric from being tr'tisted spirally, whereby the value of the article would be greatly diminished.

A'represents; frame, made of wood or other suitable materiaL'of suilicient strength' to support the other portions of thef machine. A horizontal bed, a, is arranged in the frame for holding the heating and dryingapparatus, whilethe brushing and pressing-apparatus is suspended from horizontal arms b b, which are also l pin-t of the frame A.

B-is a Vrevolving platform, arrangedon the bed a; C Care horizontal rodsor bar s, which arohingcdto the sides of' the frame A, so as to swing', sideways, but not up and dawn. The tubular fabric is packed intobasketsQafter'havirng 'been bleached or scoured, and the basketsare thea placed upon the platform B. Tho fabriojs Athen strung upon one of the` arms C, core being taken that it will not be twisted during the process, so .that the straight lines of the meshes will be retained. i

D is an upright cylinder, made of sheet m'etal',orother suitable material,'with hollow walls, so as to leave an annular hollow chamber, c, between the outdr and inn'er'walls.

Within the cylinder D is arranged another-cylinder, E, having also double walls, which enclose an annular chamber, d. Between the cylinders-D and E is loft an annular chamber, e, in which 'a spiral channel is provided, by the arrangement of a ange' or tube, which is laid Aspirally around thel inner cylinder E, and which is as wide as the chamber e. The bottom, g, of the, whole"cylinder D is made of cast iron, as shown, and from its centre projects au annular ange,-i, on which is a shoulder,- that serves to supporta sheet-metal tube, F, around the lower end of which a horizontal'annular flange orplatform, S,is 4irmly arranged. A

The top, i, ofthe cylinder is -an annular plate, whichy only covers the chambers c, d, 'and e. Two sliding plates .lc lf: covei` the space between the tube F aud'the inn'er wall of the cylinder E..

In the upper part ofthe tube F is arranged a short tube, Z, which has a spiral slot, throughwhich a pin, m, passes, which islsceured to the inside 'of the tube F.

, The covering-plate 'of the tube li's. perforated, and in its centre s a socket, for the spreader to rest in, as will be hereinafter more fully described. The tube Z can be raised or lowered, by turning it, as the pin m acts agaiust'the upper-.or lower edge of the spiral slot inl'. y y

I l n n are pipas, through which steam is conducted into the chambers and d. o` is a pipe, through which a blast of air is forced into the top'f the spiral channel e. Through a passage, p, the .lower ends of thechannel e and tube F'communicte with -each other, so that the blast of air forced into the top of the channel c passes around the inner cylinder E, through the' channel e, and thence through the passage p, into Athe tubo F, and and then out through the holcs'iri the cover of the tube Z.

` The air becomes thoroughly heated while passing through the channel e, as' the steam-vessels D and E surround it, and the air thus heated heats tbewalls oi' the tube F.

The tubular fabric, strung upon the arm C,-is now strung upon the tubs F, being gradually drawn from the former to the latter, and rests upon and is supportedby the'ange or'platform S. The coversl: k dre then closedand the fabric will be partially dried on-t'he heat-ed. tube F.. 'When'sufciently dried, the spreader G is arranged above the drying-apparatus.

Fromfthe braces btb is suspended a frame, H, or; rather two arms, in which bearings are arranged for four horizontal rollers, q q end .r and whicharms are cuimmtedl at theitlower ends and strengthened by o series of braces or bars, I I,

The spreader G consists-ofa hollow bar, s, in the centre ofwbicll the. upper end of o. vertical scre\r-bar,', is swivelled. The upper horizontal arms of two vertical velbow-bers u are fitted into the said' hollow bar s, sg as to, slide therein towards or from the neutral screwlbar t'.

rms 1 i, which are hinged to the bars u and to'nuts w, which encircle 'the screw t, connect and .hold the bare u.,

l'By turning the screw t, the nuts w are either .raised orf lowered, and .the armsv v-brougbt out of .their horizontalposition.' The aforesaid vertical arms u can'thusbe spread more or less apart, and are heldin any position by means of arjam-nut,which iaarrangedon the-screw t, between tbeznuts w w. The spreader can' thus'b'e adapted to fabrics of different diameters', A `-The bar a is placed between two of the braces I, (see fig. 2,)

is thus' prevented from turning. The cup l, of the tube F, is lowered -bet'ore the .spreader is inserted, and is then raised, so that tho lower. en d'of the screwvt is tt'ed intoethe soclret which is provided 1in. the centre of thecap l, as isolearly shown in lig. 2.

The spreader G, which consists ot'i'tlle parts s, t, u,-' o, and'w, is in'position to receive the fabric, whe'nit is heldA between the tube F and vrollers r, as ljhereinspecified'l The-lower endsof the bai-suore rounded, as-

sboirn, so. as not to injure the fabric. The fabric is, after .having bee'ngsuiciently dried, drawn from the tube F, over the spreader G, and is'thereoueupanded or attened, so as to be well led ,to thecalenderhg-rollers g-nnd f; Thecurrent of'bot airpassing out'through the p erforate'dfcap I into Vthe spread fabric, and through the meshes'o the same, .carries loti 'nllthe moisture iu the aaidfbric, and the sa'xneis thus thoroughly drie'd.

The rollers r f ara arranged one above the othsr, andabove them are the rollersq g,' which are arranged 'alongside oeach other.

'Theffabric is passed over th'ollo'wer'ioller r, and. then over the otherlroller, r, and between the neatod hollow ironing-rollers q g, as iscl'earlyshowu in g. 2, aud'is then wouu'd upon a roller, y, which is arranged in the frame H, so as tubo 'easily removed, when a suicieut'quantity of the `fabric is 'wound npoui'it.

,While on the spreader G, thcfabric can be 'ensilyadjustedA so that the lines of the meshes will be held straight by'rev'olvigtheupright tube Fa I L L'are two revolving brushes, which srearranged ou both sides of the rollers rr, and' which Vare hung in o liexible'i'rame,M'. They are pressed against the fabric, in' the mauuerzshowu in lig'. 2, so as te brush both outside faces o f the same, -therebyxincroasing its glossy'and goed appearance...

'. lhe rollers g, r, y,'s`nd Lares-evolved bymeaus ofZgearwheel'sf belts, o r any other suitable mechanism.

Iam aware that machines for drying and .finishing tubularfabrics are already iu,usebut they are all arranged horizontally, and no provision is made for preventingtho'falriofrom being twisted.-

By the use'of the vertical revolvingxtube, 'the-fabric, when once adjusted, will almost adjust itself, 'so as to romain straight, as Vthe tube turns so easily that ln.ny attempt at :twisting the fabric will make the table turn untilno more strain is`ex 'e'rted at one sideofthe tube th'aua't the other.

Having thus dcscribedmy invention, what I claim n's :longitud-desire to secure-bylaetters Patent, is-` 1. The heatingdev'ices, consisting of the-'chambers'qrdfand spiral'chamber'e, passage p, and' ltn b''Fl, in
